GRlP-HOISTING ARCH-BAR FOR CABLE CARS,

SPECIFICATION forming part of Letters Patent No. 411,907, dated October 1, 1889.

Application filed July 20, 1889. Serial No. 818,113 (No model.)

To aZZ whom it may concern.-

Be it known that I, JOHN STEPHENSON, a citizen of the United States, residing in the city, county, and State of New York, have invented certain new and useful Improvements in Grip-Hoisting Arch-Bars, of which the following is a specification.

The grip-machine of a cable car is a de tachable instrument, and is usually separated from the car at the terminus of each circuit of the road. In some cases the gripmachine is let loose from the car and allowed to remain in the slot-rail of the road while the car is moved away and another car takes its place with possession of the released gripmachine; but in this case the grip-machine is adapted to be lifted up and out of the car, which is sometimes done by the hands of one or two attendants; but as now made the gripmachine is of such weight as to require the aid of a tackle in removing it. As tram-car roofs are frail structures, 1 have found it necessary to transfer the tackle-support to the side walls of the car-body, and for this purpose I provide a metal arch-bar conforming approximately to the outline of the car-roof. This arch-bar reaches from side to side of the body, and it has at each end a hook and eye or tenon and mortise or other form of connection to a metal plate secured to the side wall of the carbody, preferably fastened to the side top rail, side pillar, head-panel, or parts adjacent. The central part of the archbar has an eye or other support for the ten1- porary hanging of a tackle adapted to be used in lifting the gripmiachine, and the crown of the arch-bar is held steadily by a brace fastened to rafters or some part of the roof structure. These parts maybe constructed in any suitable manner, but preferably as illustrated in the accompanying drawings,in which- Figure 1 is a transverse section of a carbody, showing my improvement and the mode of using it. Fig. 2 is a section on the line 2 2, Fig. 1, looking in the direction of the arrow. Fig. 3 is a detached View of the stay and ad jacent parts. p

A A are the sides, B is the bottom, and C the top, of the car.

D is the metal arch bar, having its bearings at the ends in the metallic supports or plates E E, shown as secured to the side top rails of the car, the ends of the bar having hooks i lodged in sockets in the plates, so that the bar may be lifted from its supports without detaching the latter from the car body. An extension .9 of each plate E is secured to one of the pillars F is the brace or stay secured to the rafte rs of the roof and. socketed or provided with a bearing for the arclrbar, holding the latter firmly in position without interfering with its ready removal when required.

In the car-floor is an opening for the pas sage of the cable-grip machine, which opening is closed by a trap y.

The tackle is shown supported from the arch-bar and connected with the grip car rier X.

Without limiting myself to the precise construction and arrangement of parts shown, I claim 1. A car having as part of its apparatus a cable-grip machine, and above it an arclrbar adapted'to support a tackle for lifting the cable' grip machine, substantially as and for the purpose described.

2. A car having a cable-grip below the carfloor with opening through the floor snfficient for the passage of the cable-grip machine, and over the machine and connected with the up per part of the car structure an arch-barsuitable for holding a tackle adapted to hoisting and lowering the grip-machine in and out of place in the car, substantially as and for the purpose described.

3. A. car having above a cable-grip machine an arched bar with its ends supported by the side walls of the car-body, substantially as and for the purpose described.

at. A car having a tackle supporting arched bar with its ends lodged in metal plates se cured to the side top rails of the car-body, substantially as and for the purpose described.

5. A car having a tackle-supporting archbar immediately beneath the carroof, with the ends of the arch-bar lodged in sockets or metal plates secured in part to the side pillar or other portion of the car-body, substantially as and for the purpose described.

6. A car having a tackle-supporting archbar immediately beneath the car-roof, with the end of the areh bar connected to a metal plate or socket sec ured to the side wall structure of the car-body by a detachable connection, permitting removal of the arch-bar without affecting the metal plate or socket union with the car-body, substantially as and for the purpose described.

7. A car having a tackle-supporting archbar with and a stay for supporting the crown of the arch, and adapted to permit the archbar being removed or Withdrawn from its 10 place without disturbing the crown stay or brace, substantially as and for the purpose described.

In testimony whereof I have sign ed my name to this specification in the presence of two subscribing witnesses.

JOHN STEPHENSON.
